Avа Kizer: Initiаl Pоst оn Tuberculоsis Tuberculosis (TB) is а contagious infection caused by the bacteria Mycobacterium tuberculosis. It mostly affects the lungs, but it can also spread to other parts of the body like the kidneys, spine, and brain. TB spreads through the air when someone with active TB coughs, sneezes, talks, or sings. When another person breathes in those droplets, they can become infected. After entering the body, the bacteria usually settles in the lungs first, where the immune system tries to control it. Once TB enters the lungs, the immune system responds by sending macrophages to attack the bacteria. The problem is that Mycobacterium tuberculosis has a thick, waxy coating that helps it survive inside these immune cells. Because of this, the body tries to “trap” the infection by forming granulomas, which are small clusters of immune cells. In some cases, the bacteria stay inactive inside these granulomas, which is called latent TB infection. In other cases, especially when the immune system is weak, the bacteria can become active and cause disease (Centers for Disease Control and Prevention [CDC], 2024). There are several risk factors that increase the chance of getting TB. These include living or working in crowded places, close contact with someone who has active TB, homelessness, incarceration, malnutrition, diabetes, substance use, and having a weakened immune system such as with HIV or chemotherapy. People who come from or travel to countries where TB is more common are also at higher risk (World Health Organization [WHO], 2024). Symptoms of active TB usually grow slowly. A common symptom is a cough that lasts more than three weeks. Other symptoms include coughing up blood, chest pain, fatigue, fever, night sweats, weight loss, and loss of appetite. If TB spreads outside the lungs, symptoms can depend on the area affected. For example, TB in the spine can cause back pain, and TB in the brain (TB meningitis) can cause confusion, headaches, and neurological symptoms. Latent TB does not cause any symptoms, which is why people can have it without knowing. To diagnose TB, healthcare providers use a mix of tests. The tuberculin skin test (TST) and blood tests called interferon-gamma release assays (IGRAs) help show if someone has been exposed to TB. A chest X-ray can show signs of infection in the lungs, like spots or cavities. To confirm active TB, sputum samples are tested for acid-fast bacilli (AFB), and cultures or molecular tests (NAATs) can identify the bacteria and check for drug resistance (CDC, 2024). Treatment for TB takes a long time because the bacteria grow slowly and can hide in the body. For drug-susceptible TB, treatment usually starts with four medications: isoniazid, rifampin, pyrazinamide, and ethambutol for about two months. After that, treatment continues with isoniazid and rifampin for another four to seven months. It is really important that patients finish all their medication, even if they start feeling better, because stopping early can lead to drug resistance or relapse. Some patients may have drug-resistant TB, which is harder to treat and requires stronger medications for a longer time, sometimes 18 months or more. These medications can also have more side effects, so patients need close monitoring. Nurses play a big role in TB care. One of the most important things is infection control. Patients with active TB need airborne precautions, which means placing them in a negative-pressure room and wearing an N95 mask. Nurses also educate patients about taking their medications correctly and finishing the full treatment. Since TB is a reportable disease, nurses also help notify public health departments so that contacts can be traced and tested. Emotional support is also important because patients may feel isolated due to long treatment and infection precautions. Prevention of TB includes early detection and treatment of latent TB, screening high-risk groups, improving ventilation in crowded areas, and using the BCG vaccine in countries where TB is common. According to the WHO (2024), treating latent TB is one of the most important ways to reduce new cases of active TB worldwide. Overall, TB is still a serious global health problem, but it is preventable and treatable. The key is early diagnosis, proper medication adherence, and good infection control practices. Nurses are very important in helping patients stay on treatment and preventing the spread of infection in the community. References Centers for Disease Control and Prevention. (2024).

Althоugh Tim wаs experiencing а periоd оf deep depression severаl weeks ago, he now finds himself in an extremely excitable and elevated state of mind. He feels so high on life that he quit his job, packed up a bag, emptied his savings account, and left his wife and kids to embark on a cross-country motorcycle journey. Based on Tim's likely mental disorder (guess which one), which of the following is likely to be true about Tim?
Apprоximаtely whаt percentаge оf peоple have some form of a personality disorder?
Which оf the fоllоwing is chаrаcteristic of people with obsessive-compulsive personаlity disorder?
